A total of 70 holes were drilled for 4,671 metres, testing several high-grade gold-in-saprolite auger geochemical anomalies to better understand the style, nature and potential host of the mineralisation.
The results are from 20 holes drilled on the Eastern and Western flank targets at Diamba Sud, while results from a further 22 hole are pending.
An induced polarisation (IP) survey over the Northern Arc and Western Flank targets is planned to start this month, which will assist in interpreting drill results and the search for possible host structures.
Chesser managing director & CEO Mike Brown said the ongoing success of Diamba Sud’s drilling was very encouraging, with high-grade gold mineralisation now being encountered in other areas of the extensive gold geochemical anomaly.
The recent results include 6 metres at 7.79 g/t gold from 39 metres, 4 metres at 6.85 g/t from 20 metres, 4 metres at 2.98 g/t from 4 metres and 16 metres at 1.05 g/t from 4 metres.
The intersection of 6 metres at 7.79 g/t, along with historical drilling results to the south, artisanal mining activity and a coincident airborne magnetic feature, outlines a potential mineralised structure of at least 2 kilometres in strike length.
Brown continued: “In particular, the intersection of 6 metres at 7.79 g/t gold in the north of the Western Flank target indicates a strike extent of more than 2 kilometres for this potential north-trending mineralised zone.
“This target, along with other areas already identified, will be the focus of the follow-up phase-two drilling program.
“[This] will commence once all assay results are received and integrated with the planned induced polarisation geophysical survey.”
Diambu Sud covers more than 53 square kilometres and is about 2 kilometres to the west of the Senegal-Mali shear zone, a major regional structure host to numerous multi-million-ounce gold deposits.
The northern block of Diamba Sud also immediately adjoins an open pit gold mine operated by Afrigold.
